Hi pekos, thats a beauty of a flier. Are you really pulling over 230A with the Vasa fan? What controller are you using? The L-39 flies great. Whats the AUW for your bird? The wing certainty handles it well.

I'm so glad they removed the helis from our local flying field.
All i could think of when hearing all the helis in the background is, I hope someone is there looking out for both you and your camera man.
